Delta Electronics Series Q48SB Specification Sheet

Delphi Series Q48SB, 300W Bus Converter
DC/DC Power Modules: 48V in, 12V/25A out
The Delphi Series Q48SB, 48V input, single output, quarter brick,
300W bus converters are the latest offering from a world leader in
power systems technology and manufacturing -- Delta Electronics,
Inc. This product family supports intermediate bus architectures and
powers multiple downstream non-isolated point-of-load (POL)
converters. The Delphi Series Q48SB operates from a nominal 48V
input and provides up to 300W of power or 28A of output current in
an industry standard quarter brick footprint. The Q48SB product
currently supports two input ranges: the Q48SB120 features an input
voltage range of 42V to 53V and provides an unregulated output of
12V at 20A or 25A. The Q48SB108 features a wider input voltage
range of 36V to 60V and provides an unregulated output of 10.8V at
up to 28A. Typical efficiency for the 12V/25A module is 96%. With
optimized component placement, creative design topology, and
numerous patented technologies, the Q48SB bus converter delivers
outstanding electrical and thermal performance. An optional heatsink
is available for harsh thermal requirements.
